• New lesson — "Your First Full Game": a complete hand start to finish — turn order, getting skipped, and reading the payout.
• Smarter practice: opponents are read from their visible tiles, and the coach no longer suggests discarding from a hand you could already win.
• Purchases made clearer: better cross-device Restore, a Family Sharing note, and an easier way to reach us.
• Reliability + latest store billing under the hood.
• Plenty of polish and small fixes.
2.6.33 8월 5일
NEW — Score game night together!
In Host Mode, start a table and share the code: now everyone keeps score from their own phone, all in sync. Record each hand, watch the running tally and the who-pays-whom settle-up, and let the deal rotate automatically. Prefer to run it solo on one phone? That still works too.
Plus more teaching and polish throughout. Happy playing!

Bug fixes and polish, more accurate lesson progress on hands that use jokers, clearer screen-reader labels, and reliability improvements.

• New "Do you want to be East?" choice before each game.
• VoiceOver and accessibility improvements throughout.
• Reliability and polish: fixed a table-hint seat-name mix-up, steadier gameplay, and a smoother in-app experience.
